The clinical effect comparision of miniplates and kirschner-wires fixation of metacarpal or phalanx fractures

Objective To compare the clinical effect of mini-nickeclad and Kirschner-wire for fractures of metacarpal and phalanx.Methods L、Tshapes or straight plates were fixed at the dorsal or lateral side of metacarpal or phalanx in miniplates group;crossed Kirschner-wire or single Kirschner-wire were adopted in Kirschner-wire fixation group;all injuried tendons were repaired at the same time.We evaluated the total range of motion(TAFS score),operating time,hospital time,infection rate and time of fractures union in both groups.Results In miniplates fixation group,the mean operating times is 40 minutes,mean hospital time is 5.3 days,mean rate of wound infection is 2.4%.in Kirschner-wire group,the mean operating time is 25 minutes,mean hospital time is 4.8days,mean rate of wound infection is 20%,mean time of fractures union is 9 weeks,and by TAFS score rate of fineness is 71.4%.The data of rate of wound infection and TAFS score of fineness shows statistical difference.Conclusion The miniplates decrease the rate of wound infection,and improve the movement range of involved finger.
